# Battery Testing vs ECO Battery

The clearest difference is review sentiment: ECO Battery at 64% against Battery Testing's 23%. ECO Battery also leads on in-app purchases (none vs 1) and ads (none vs shown). Battery Testing's advantage is rating (4.5 vs 3.9) and ratings volume (12K vs 19). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Battery Testing sells 1 one-off in-app purchase. ECO Battery asks for nothing beyond the download.

Battery Testing holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Battery Testing has 12K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 23% of Battery Testing's written reviews are positive against 64% of ECO Battery's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 24, 2026 and September 9, 2026 respectively.
